Definitions
- Water activity abbreviated “Aw”, also referred to as “equilibrium relative humidity” or “free water” is the ratio of water vapor pressure to above the surface of a body and the vapor pressure above pure water at the same temperature. The measurement of this water activity makes it possible to predict the water exchanges between a product and the environment in which it is located.
- a sample of this product is introduced into the hygrometer, and then the sample is allowed to equilibrate by phenomena of diffusion and change of state of the water it contains, with a captive air volume of the hygrometer. Once the equilibrium reached, which is in particular dependent on the conditions of temperature and pressure prevailing in the medium, the degree of humidity of the volume of air exposed to the sample is measured in order to deduce the quantity of free water thereof. sample.
- sample handling requires constant and sustained attention from the operator and may lead to incidents, such as cup rollovers or confusions in the identification of samples and / or in the order in which these must be analyzed.
- An object of the invention is to provide a device for automatically feeding in open sample containers an analysis apparatus, a device overcoming the drawbacks enumerated above, providing a productive time saving, guaranteeing the security of the sample transfers, while allowing a simple, safe and fast management of the samples.
- US 5,606,153 discloses an installation in which the means for storing open containers, the one-to-one transfer means of the containers and the measuring means are arranged in a chamber under controlled atmosphere, in temperature and hygrometry.
- Such an arrangement that is very expensive, can not be applied to all measurements of the sample characteristics and, in particular to that of temperature and hygrometry, because, before the measuring operation begins, these physical quantities would be altered by the controlled environment.
- the invention therefore relates to an automatic feeding device comprising:
- a measurement zone arranged beneath an analysis or measurement head
- a storage area downstream of the containers analyzed, and means able to automatically transfer each sample container from one zone to another.
- the upstream storage zone comprises:
- a store with vertical tubular passage adapted to receive a stack of sample containers, stack in which the contents of each container is confined by pressing on its upper opening of the bottom of the superimposed container, the open lower end of the said magazine being raised above a work surface and sliding to let only the container at the base of the stack, when it is biased in transverse translation by transfer means,
- a holding pusher adapted to support the pile between the moment when it is no longer supported by the base container and that where it rests on the work plan.
- the superposition of the containers ensures the containment of their contents and the preservation of the characteristics of the samples waiting for analysis, while the automatic manipulation of each of them, in the order of their introduction in the tubular corridor, eliminates any risk of presentation errors that may affect the interpretation of the measured quantity and any influence on the measurement of manual contact.
- the objects assigned to the invention are also achieved by means of a transfer method under the head of an analysis apparatus comprising an extraction sub-step subdivided into:
- C 1a a first phase of partial extraction during which the arm of the transfer means displaces the receptacle situated at the base of the stack resting on the stop surface of the working plane, so that this receptacle makes projecting laterally out of the pile and away from the trajectory of the holding pusher, while ensuring the support of the rest of the pile of containers by pressing
- FIG. 1 is a perspective view of the device when its upstream storage magazine is in the open position
- FIGS. 2 to 9 are partial front and perspective views of the device and the hygrometer, during the various steps of a method for evaluating the humidity of the samples contained in open containers;
- FIG. 10 is a partial elevational view and plan on top, showing, on an enlarged scale, an embodiment of the means for transferring containers between the various areas of the device.
- reference numeral 1 designates a mirror hygrometer for analyzing a sample of substance 2 by performing an indirect measurement which consists in determining the degree of humidity of a previously equilibrated air volume with said sample.
- This measuring apparatus therefore comprises a measuring zone 3 intended to receive and position at least one sample receptacle 4 containing the substance 2 to be analyzed.
- the hygrometer 1 comprises a measuring head 5 adapted to receive the sample container 4 and containing the instrumentation necessary for carrying out the measurement of humidity.
- the measuring head 5 is carried by the main body 6 of a desk containing electrical supply means and control and programming means, respectively, measuring means, the device for container feeding and motorization means automated functions.
- the measuring head 5 is disposed in a casing 7 equipped with a cylindrical opening capable of sealingly surround a cylindrical container 4.
- This casing 7 is connected to means able to move it between, a position of clearance, shown in Figures 1 to 6, wherein the containers 4 can freely circulate on the horizontal work plane 8 of the desk, and a measuring position, shown in Figure 7, wherein the housing 7 cap sealing the container 4 stopped in the measurement zone 3.
- the casing 7 delimits inside the measuring head 5 a volume of captive air with which the sample of substance 2 can equilibrate.
- the casing 7 is hinged to the body 6 by a hinge and is connected to a motor, not shown, which can rotate it about this hinge, but in a variant it can be connected to an electric jack or other, moving it between its two positions of clearance and measurement.
- sample container 4 designates containers comprising a bottom and a substantially cylindrical edge wall and whose upper opening can be closed by the bottom of the container stacked on it. When the container is in the measuring head, its opening allows all exchanges between the volume of captive air in this head 5 and the analyte 2 to achieve a fast and reliable balance.
- FIG. 1 shows that the measuring zone 3 of the apparatus 1 is disposed between an upstream storage area 10 of a stack 16 of sample holding receptacles 4, awaiting analysis, and a downstream storage area 31 of the receptacles analyzes.
- the apparatus 1 is equipped with transfer means 11 able to automatically move the sample container 4 from the upstream storage zone 10 to the measurement zone 3, then from the measurement zone 3 to the downstream storage zone 31.
- upstream and downstream are given with reference to the direction of movement according to the arrow 40 of the containers 4 on the worktop 8.
- the upstream storage zone 10 comprises a magazine 14 provided with stacking means 15 capable of forming a stack 16 of sample containers 4a, 4b, 4c, 4d, 4e, 4f, whose 4a is based on a stop surface 23 forming part of the work plan.
- the stacking means 15 consist of the cylindrical and vertical internal corridor 18 of a storage column 17 constituting the magazine 14.
- the column 17 is formed by the union of a fixed half shell 17A and a removable half-shell 17B, for example articulated on a hinge, these half-shells being assembled so reversible in the direction of the length.
- the column can be opened in the direction of its length to allow direct access to its inner corridor 18.
- the removable half shell 17B is not shown, to allow viewing of the container door sample 4.
- the internal diameter of the cylindrical passage 18 substantially corresponds to the outside diameter of the sample holder 4 and its bore is adjusted so that it has a low functional clearance with the containers, play allowing during their vertical sliding by gravity action, to benefit from pneumatic braking by the air trapped beneath them.
- Stacking means means means capable of aiding the formation of a stack of sample containers 4, and in particular able to align and center said containers relative to each other, and then to maintain the stack. 16 formed. These means contribute to the formation of confinement means 12 able to prevent or limit the exposure to ambient air of the substance or substances 2 contained in the sample receptacle (s) 4. In particular, these confinement means 12 have in order to maintain the substances to be analyzed in a substantially sealed closed volume, so as to avoid a significant change in their state before the analysis. For example, these confinement means limit an exposure of the sample to the ambient dry air to avoid alteration of said sample, in particular by drying or partially humidifying it.
- the containment means are constituted by the bottom of each sample holder 4 of the stack 16 which cooperates with the upper edge of the opening of the peripheral wall of the container located below it.
- the passage 18 of the magazine 14 opens at the top of the column 17 and forms the loading port through which each container 4 is introduced into the magazine.
- This corridor also opens out of the lower end of the magazine 14, which end is itself arranged in elevation of the stop zone 23 of the worktop 8 to let only the container 4a disposed at the base of the stack 16 when it is solicited by the transfer means 11.
- the magazine is mounted on the body of the apparatus panel 1 permanently or removably.
- the automatic feeding device also comprises an operating element 20 placed under the stack 16 of containers 4 and constituted by a pusher 21.
- This holding pusher is disposed vertically below the stop surface 23 and is connected to means able to move it vertically between a rest position, in which it is retracted under the plate, and a position in which it is supported under the bottom of the lower container of the stack 16 by a circular plate 22.
- This plate crosses the work plane by a circular opening 8A having, like it, a diameter smaller than the outside diameter of A container 4.
- the transfer means 11 of each sample container 4 on the worktop 8 comprise, as shown on an enlarged scale in Fig. 10, an arm 26 which, extending perpendicular to the direction of movement, represented by FIG. 40, is articulated on a vertical pivot 28, substantially normal to the work plane 8.
- This pivot is carried by the carriage 27 'motorized drive means 27 arranged under the work plan, and can move the carriage and the arm between a rest position, in which the arm 26 is upstream of the upstream storage area 10, as shown in Figure 2, and a downstream end position, in which the same arm is near the entrance 34 of the downstream storage area 31, as shown in Figure 8.
- Figure 10 shows that the arm 26 has the shape of a substantially rectangular section beam in which is formed a footprint 26A complementary to the outer form of a container 4, and, for example, in a circular arc, so as to improve the grip on it during the transfer,
- the height h of the arm 26 is, at least in its part coming under the magazine 14, substantially less than the height of a container, to allow it to pass between the stop surface 23 holding the stack 16 and the lower end of the magazine 14, without it being able to come into contact with more than one container at a time.
- Figure 10 shows that the arm 26 may, under the effect of a folding torque C p exerted on it by the container of the foot of the stack, pivot around the pivot 28, to fold and move back.
- the arm 26 comprises an elastic return means 29, such as a torsion spring, exerting a deployment torque C d substantially opposite the folding torque C p .
- the elastic return means 29 allows the arm to reposition itself by redeploying, after the folding torque C p has been relaxed, to adopt an orientation substantially perpendicular to the direction of its translational movement, such that the 'illustrates the dotted representation in Figure 10.
- the amplitude of the pivoting of the arm 26 about its axis 28 is limited by an abutment means 30 which is antagonistic to the elastic return means 29.
- the combination of the elastic return means 29 and the abutment 30 constitutes an anti-rotation means. return allowing the arm 26 to transmit a driving force to the sample container 4 in the direction of travel along the arrow 40, that is to say in the direction of movement between the upstream storage zone 10 to the zone 3.
- the work surface 8 of the main body 6 comprises, especially in the region where it constitutes a sliding track for each sample container 4, a low-temperature coating 25. coefficient of friction, such as a release material, for example PTFE, better known under the trademark Teflon.
- the analysis apparatus 1 comprises a downstream storage area 31 able to accommodate the sample holder or containers 4 after analysis of the substance or 2 they contain.
- This zone is formed by a plate 32, removable or not, comprising a means of ordering the sample holding containers 4 reaching the downstream storage zone 31, and for example a spiral groove 33 whose width substantially corresponds to the diameter of the containers sample holder 4.
- the zone 31 is preceded by an inlet zone 34 provided with guide means 35 for guiding the containers 4, and more precisely for aligning and / or centering the latter under the effect of the force motor provided by the arm 26, such as lateral ribs limiting or tightening the movement of the containers 4 on the track 25.
- the device comprises, in the analysis apparatus 1, various control means related to automation, such as presence sensors capable of monitoring the disposition of the sample containers, for example to avoid collisions, or means for identifying the containers, for example by barcode. More particularly, it comprises at least one presence sensor, disposed at the measurement station 3 and reacting on the control means of the transfer means 11 to cause the arm 26 to retract before lowering the casing 7 of the measuring head 5 against the work plan 8.
- the system with an articulated arm on a carriage movable transversely to the arm allows to combine compactness, simplicity of manufacture and lightness of the mobile structure, and, consequently, energy saving.
- the relative movement of the approximation between the measuring head 5 and the sample holder 4 is ensured by moving said container, for example, using a pushing member moving the container between the work plane and the head.
- the first step A is the loading step in which is placed in the store 14 of the upstream storage area 10 at least one sample holder 4 loaded substance 2 to be analyzed.
- Each container is introduced from the top of the passage 18, either individually or in the form of a stack 16, contained for example in a basket, each of these operations being carried out manually or by means of automated loading means or semi-automated.
- the stacking at the top of the column 17 makes it possible to feed the storage area 10 at any time, and thus to complete the stack 16 while the apparatus 1 is in the process of analyzing a sample.
- the first charging step A comprises a sub-step A1 for preparing the magazine, during which, successively, the magazine 14 is opened, by pivoting the half-shell 17B, the pusher 21 is raised until its tray 22 is in the magazine, a first container 4a is placed on the plate 22, then the magazine 14 is closed.
- the container 4a thus forms a plug closing the base of the column, to the functional clearance.
- the other containers for example 4b to 4h which are introduced from the top of the column 17, unitarily or stack, and which descend by gravity to contact with the container 4a, under jacent and stopped, are guided in their stacking by the corridor 18 and are subject to a pneumatic braking by the air that each of them moves and that can escape only partially from the bottom of the column closed by the container 4a.
- the magazine 14 is in the situation of FIG. 2. It is specified that when the interval between two loadings may be likely to favor the alteration of the sample by the ambient atmosphere. , an empty container is placed on the upper container of the stack to seal the underlying container by its bottom. This empty container is removed later, when it leaves the store or when it reaches the measuring head, by a manual or automatic operation, the latter can be triggered by a sensor analyzing the absence of sample in the container.
- step B shown in FIG. 3, the pusher 21 is moved vertically downward, until its tray 22 is retracted under the working plane 8 to allow the first container 4a of the stack 16 to rest on the stop surface 23 and no longer be in the magazine 14, but below.
- the plate 22 is no longer in contact with the battery 16, whose entire load is applied to the stop surface 23.
- the next transfer step C of moving each sample holder 4 from the storage area 10 to the measurement zone 3, comprises a sub-extraction step C1, itself subdivided into two phases C1a and C1b.
- the arm 26 which was initially upstream of the storage zone 10 is moved in translation in the direction of the arrow 40 until it comes into contact with the sample container 4a. located at the base of the stack 16, below the magazine 14. Once in engagement with the container, the arm 26 transmits its movement and slides on the stop surface 23 by shifting it transversely out of the stack and hole 8A for the passage of the plate 22 of the pusher 21.
- the container 4a provides support for the rest of the stack of containers 4b to 4f by pressing on the edge of its opening of the bottom of the container 4b, located immediately at above him.
- all the containers of the stack 16 are prevented from falling downwards and can not jam by jamming in the corridor 18, thanks to the weak functional clearance between corridor and containers.
- the pusher 21 is moved vertically upwards until its plate 22 comes into contact with the bottom of the container 4b, still supported by its downstream side by the container 4a.
- This short phase is inserted in the duration of the previous so that the movement of the arm 26 and the container 4a is continuous, smoothly and allows to complete the extraction of said container from the upstream storage area 10, before passing to a substep C2 end of the transfer to the measurement zone 3.
- a step D starting as soon as the container reaches the area 3 and is marked by a presence sensor, it controls the recoil of the arm 26, so that it comes in a position shown in FIG. 7.
- a step F starting as soon as the step E of analysis of the substance 2 is complete, the control means of the device trigger the raising of the head 5, in order to clear the path of movement of the arm 26 towards the storage area 31, then this arm 26 is moved to slide the container analyzed to the inlet area 34, as shown in Figure 8.
- the force transmitted by the arm 26 pushes the previous containers step by step and allows them to accumulate in the spiral groove 33 until they are evacuated, washed or transferred to another analysis apparatus.
- the arm 26 is subjected to a backward movement in the direction of the arrow R , opposed to the inflow of containers indicated by the arrow 40.
- This recoil movement allows it to rearm, that is to say to position upstream of the storage area 10, so as to transfer a new sample holder 4b of said upstream storage area 10 to the measuring zone 3, in particular repeating the steps A to F described above.
- the free end 26B of the arm 26 meets the next container 4b or the pusher 21 if it still holds the remaining battery 4b, 4c, 4d, 4e, 4f in the corridor 18, as this is shown in Figure 10. Due to its articulated structure, the arm 26 is erased under the effect of the folding torque Cp resulting from the application of the tensile force exerted on the carriage 27 at the means of drive 27 and the retaining force due to contact of the free end of said arm with the pusher 21. Thus, the arm 26 folds and retracts so as to continue its recoil.
- the folding of the arm 26 has the effect of banding the elastic return means 29, so that, once crossed the obstacle constituted by the pusher 21, said biasing means redeploys the arm 26 against its abutment means so that he finds at the end of the cycle his initial orientation, illustrated by the dotted lines in Figure 10, and his initial position upstream of the upstream storage means 10, as shown in Figure 2.
- the feeder is ready to start a new cycle.
- the hygrometer 1 is then ready to transfer the next sample container 4b from the upstream storage zone 10 to the measurement zone 3.
- the feed device for analysis apparatus makes it possible to automate the measurements or analysis of the characteristics of the samples and to organize them in series corresponding, for example, to production batches.
- the feeding device makes it possible to release the operator from tedious handling tasks that have no real added value, and to make it available for other activities.
- the automatic feeding device secures the sample transfers, on the one hand, by carrying out their storage before analysis in conditions favorable to the conservation of the physico-chemical characteristics of the substances to be analyzed, and, on the other hand, by considerably limiting the risk of false maneuver or clumsiness leading to the loss of a sample or the confusion between several samples.
